vlog: New vlog/enable-rate-limit and vlog/disable-rate-limit commands.

Browse Source 
A few times while troubleshooting it would have been useful to get
complete logs, rather than post-rate-limiting snapshots of them.  These
ovs-appctl commands make that possible.

By default, \fB\*(PN\fR limits the rate at which certain messages can
be logged. When a message would appear more frequently than the
limit, it is suppressed. This saves disk space, makes logs easier to
read, and speeds up execution, but occasionally troubleshooting
requires more detail. Therefore, \fBvlog/disable\-rate\-limit\fR
allows rate limits to be disabled at the level of an individual log
module. Specify one or more module names, as displayed by the
\fBvlog/list\fR command. Specifying either no module names at all or
the keyword \fBany\fR disables rate limits for every log module.

The \fBvlog/enable\-rate\-limit\fR command, whose syntax is the same
as \fBvlog/disable\-rate\-limit\fR, can be used to re-enable a rate
limit that was previously disabled.
